A class that defines if and how geometry is included in query results from a layer.

Description |
|
FormatValuesInResults |
bool |
Use field formatting defined for the layer in the source map. Number values will be converted to string. Default is true. If false, formatting will be ignored. |
|
GeometryResultOptions |
Define how geometry is modified when returned in query results. Operations include densify and generalize. IncludeGeometry must be set to true. | |
|
IncludeGeometry |
bool |
Define if geometry should be included in query results. Default is true. |
|
ReturnFieldNamesInResults |
bool |
Include field aliases in query results. Default is false. If true, the original field names will be returned. |
Remarks
In general, this object is used to indicate
if and how geometry is included in query results. In
some cases you may want modify geometry returned from a query to enhance
performance or enable compatibility. If geometry
is not necessary, set IncludeGeometry
to False and query results will not include geometry. If
geometry is included, you can modify its content through densify or generalize
operations defined via GeometryResultOptions.
Densification is used to support clients that do not support non-linear
geometry such as Bezier and Circular Arcs. Generalization
reduces the number of vertices in geometry which reduces the amount of
data returned to the client and improves query response time.
FormatValuesInResults and ReturnFieldNamesInResults
are only applied to Find and Identify
map service methods. They are ignored by QueryFeatureData2,
QueryFeatureIDs2, QueryFeatureCount2
and QueryHyperLinks methods.
The default values for FormatValuesInResults
and ReturnFieldNamesInResults
are True and False respectively &endash; that means if they are not set
explicitly, those functions will respect field formatting and field alias
set in the source map document. That means values are converted to a string
in the result. When FormatValuesInResults
is set to False, the numerical results of the query will be not be formatted.
When ReturnFieldNamesInResults
is set to True, the results will display original field names.
